ABSTRACT
A 54-year-old-woman with narrow QRS tachycardia (heart rate, 210 beats per minute) was admitted to the authors' hospital. Tachycardia terminated after administration of adenosine. The 12-lead electrocardiogram after conversion to sinus rhythm was unremarkable. During electrophysiological study, tachycardia could be easily induced by programmed atrial stimulation without jump phenomenon. The cycle length was 260â¯ms. During tachycardia, the atrial activation sequence in the coronary sinus (CS) was distal-to-proximal. However, during decremental ventricular pacing, retrograde conduction showed exclusively proximal-to-distal activation in the CS. What is the underlying mechanism?
